Evolution and Innovation in Autotransplantation with a Complete Digital Approach

Thu 26 Jan | 10:40 - 10:50

Autotransplantation is a well-documented surgical procedure for replacing missing teeth. The procedure entails moving a tooth from its natural location to a surgically prepared recipient site inside the same person after extraction or transplanting it from its original location. A successful autotransplanted tooth, in contrast to a dental implant, permits alveolar growth in synchrony with neighbouring teeth, and the periodontal ligament (PDL) of the donor tooth has the ability to encourage the development of new bone, gingiva, and PDL at the recipient site. Additionally, orthodontic pressures can be used to shift the grafts. The difficulty of attaining periodontal and pulp healing of the grafted tooth is the biological restriction of autotransplantation.

Studies reporting autotransplantation outcomes with up to 40 years of follow-up and comparing these results to outcomes of implants and other prosthodontics choices are used to evaluate the success of autotransplantation using certain criteria. A successful autotransplant would be one that endures until the majority of vertical face growth is finished. For that specific time period, such an autotransplant would have met its functional, biological, and cosmetic goals; alternative solutions are now available.

The amount of extraoral time before transplantation must be kept to an absolute minimum. Less than a minute of extraoral time has been found to drastically lower the incidence of pulp necrosis. The vitality of the periodontal ligament, which drastically declines with increased extraoral exposure, is the most crucial element for success.

The recipient site can be prepared using a template or a duplicate of a tooth to cut down on extraoral time and handling of the periodontal ligament.

From a segmented cone beam image, three-dimensional printing offers the ability to produce personalized pre-surgical tooth templates. According to certain research, extraoral time was reduced from 3 to 10 minutes in the past control approach to less than a minute.

The key to success is good surgical technique and a well-developed surgical plan. The key to this kind of treatment is CBCT. Although not new, autotransplantation has become more common due to the development of technology and 3D printing. This method has significantly increased in predictability.
